Hi Jos, I have had to deal with this myself. I only remember a few of the things I tried, but not what actually resolved it.

Some ideas off the top of my head:

1. Check to make sure that you are not setting focus but rather setting the active page to switch pages and that no code is running on the other 'inactive' pages when that is done (confusing VFP as to which page should have focus).
2. Try another video driver.
3. Move the grid off the page (out of view) when you are not on the page with the grid and put it back when the page with the grid is the active page.
4. Place an opaque shape behind the grid - does it still occur?


>Hi All. I have seen related messages to this problem but cannot remember the solution. I have a form with a pageframe. Page 2 has a grid. A button on Page 2 can activate page 3. When Page 3 activates parts of the grid from Page 2 shows through in between the controls on Page 3. Any solution? Turning themes off would be ug-a-lee. (Update - turning themes off doesnt help).
